(apart from the chronograph) - I am choosing between the white dial 15400 and the black diver. I tried the black 15400 on and I actually quite like it, but feel that the white dial shows off the tapisserie dial better (more colour shift).
Interestingly, in a Hodinkee article about Jack Heuer today, he mentions the inspiration for the PVD black Monaco was seeing Spain's King Juan Carlos I wearing a black Royal Oak.
